Study Summary

An endotoxin challenge will be administered to healthy subjects to induce production of inflammatory markers. An investigational drug or placebo will be administered prior to the endotoxin challenge to assess the effect of the investigational drug on the markers of inflammation. Safety and tolerability will also be assessed.

Primary Outcome

MPO is a heme-containing peroxidase enzyme produced in the bone marrow and stored in the azurophilic granules of neutrophils, where it constitutes up to 5% of the cellular protein. Since PF-06282999 is a mechanism-based inactivator of MPO, it is of interest to evaluate the level of MPO activity in order to investigate the inhibition activity of PF-06282999.
